N-Heterocyclic carbenes (NHCs) were found to catalyze the silyl transfer from trialkylsilyl ketene acetals to ketones. In the presence of a catalytic amount of NHC 3 (IAd, 0.1 to 5 mol%), a series of enolizable ketones as well as cyclohexanecarboxaldehyde
INTRAMOLECULAR PHOTOCYCLOADDITION OF ENONE-ACETALS
Pirrung, Michael C.,Thomson, Stephen A.

Lewis acid catalyzed condensation of unsaturated orthoformates with dienol ethers gives enone-acetals suitable for intramolecular photocycloadditions, yielding heterocyclic precursors to sesquiterpene lactones.
